Their claims on the site is bogus plus having one of their customers service representative talk to me like I was an idiot. I was told the exhaust manifolds wouldn't come with the engine if the catalytic converters couldn't be removed. The last i checked there are no catalytic converters between the manifolds and turbo on a 7.3 powerstroke. In turn it cost me about 900 dollars move than it should have to buy an engine from them and put it in.
You reached out to us months after placing an order, we would have replaced the exhaust manifolds had you asked. You simply told us you had already sourced them, the rep was giving an explanation as to why they were not there. As far as the extra money you claim to have spent, we would have required the manifold gaskets to be changed anyway, you could have used the existing manifolds from your original motor.
